The connecting rod assembly comprises long connecting rods and short connecting rods, the two ends of the long connecting rod are respectively inserted into two four-corner connectors, one end of the short connecting rod is rotatably connected to the four-corner connector, and the other end of the short connecting rod is rotatably connected to the U-shaped connector, the fixing member is fixedly connected with the middle part of the long connecting rod.

As an improvement, the lower ends of support rods C are provided with rod covers.

As an improvement, one side of the seat surface is provided with a storage bag.

Compared with the prior art, the invention has the following advantages: the seat surface and the seat can be separated, the seat can be completely folded and stored, the occupied volume is small, the folding and storing of the folding chair is more convenient and quick, which improves people's use experience.

5. SPECIFIC EMBODIMENT OF THE INVENTION

Embodiments of the invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions. In the description of the invention, it should be understood that the orientation or positional relationship indicated by the terms “upper”, “lower”, “front”, “back”, “left”, “right”, “inner”, “outer”, “vertical”, “circumferential”, and so on are based on the orientation or positional relationship shown in the accompanying drawings, only for the convenience of describing the invention and simplifying the description, rather than indicating or implying that the indicated device or element must have a specific orientation, as well as a specific orientation structure and operation, therefore, it should not be construed as a limitation of the invention.

Combined with FIG. 1-7 , a portable folding dual-purpose chair, comprising a seat surface 1 and a seat, the seat comprises a support rod assembly, a connecting rod assembly, U-shaped connectors 2, four-corner connectors 3 and fixing members 4;

The support rod assembly comprises support rods A 5, support rods B 6 and support rods C 7, the support rod A 5 is a three-section folding sleeve rod, the upper ends of the support rods A 5 cooperate with the two corners of the higher position of the seat surface 1, and the lower ends of the support rods A 5 are inserted into the four-corner connectors 3 to form the detachable mechanism, the upper ends of the support rods B 6 cooperate with the two corners of the lower position of the seat surface 1, and the lower ends of the support rods B 6 are inserted into the four-corner connectors 3 to form the detachable mechanism, the upper ends of the support rods C 7 are inserted into the four-corner connectors 3 to form the detachable mechanism;

The connecting rod assembly comprises long connecting rods 8 and short connecting rods 9, the two ends of the long connecting rod 8 are respectively inserted into two four-corner connectors 3, one end of the short connecting rod 9 is rotatably connected to the four-corner connector 3, and the other end of the short connecting rod 9 is rotatably connected to the U-shaped connector 2, the fixing member 4 is fixedly connected with the middle part of the long connecting rod 8.

The lower ends of support rods C 7 are provided with rod covers 10, which are used to protect the bottom of the folding chair and improve user's experience.
